| 摘 要： | 棕紫泥土在四川约有1·6642×106hm2,占石灰性紫色土亚类的39·27%。在四川旱耕地资源中占有重要的地位,其生产潜力大,问题也多。本文运用土壤养分系统研究法探讨了四川棕紫泥土的供肥状况及主要营养影响因子。结果表明N、P是棕紫泥土作物生长的主要影响因子,补充N、P是增产的重要措施;其他营养元素是否成为影响因子要因作物而异。 |
| 关 键 词： | 棕紫泥土 作物生长 影响因子 |

| Abstract: | The area brown purple soil of Sichuan province is about 166.42×104?hm2, which is acupied 39.37% of calcareous purple soil sub-kind. Dry farmland resource has a vital status in Sichuan province. The troughput is very large, there are many matters in it. The nutrient supply and main nutrient obstracte factors of brown purple soil of Sichuan province are studied in this experiment following the systematic approach. The results show that N.P is the limiting factors on crop growth, and the supplied N.P is the important increasing production measure, other nutrient factors becoming or not the limiting factors depended different crops. |
| Keywords: | brown purple soil crop growth measure, other nutrient factors becoming or not limiting factors |
